As shown in FIG. 1, the middle frame 12 includes a first middle frame 121, a second middle frame 122, and a plurality of sliding components 123. In one embodiment, the first middle frame 121 includes a first outer frame 1211 and a second outer frame 1212. The first outer frame 1211 corresponds to the second outer frame 1212. The second middle frame 122 includes a third outer frame 1221 and a fourth outer frame 1222. The third outer frame 1221 corresponds to the fourth outer frame 1222.

In one embodiment, both a lateral surface of the first middle frame 121 and a lateral surface of the second middle frame 122 are provided with a first attachment component 124. Specifically, the first outer frame 1211, the second outer frame 1212, the third outer frame 1221, and the fourth outer frame 1222 are provided with the first attachment component 124. The first attachment component 124 corresponds to the second attachment components 114 disposed on the lateral surfaces of the second back housing 112 and the third back housing 113. When the display device 1 is assembled, the second back housing 112 is attached to the first middle frame 121 by the first attachment component 124 and the second attachment component 114, and the third back housing 113 is attached to the second middle frame 122 by the first attachment component 124 and the second attachment component 114.

Specifically, when the second attachment component 114 is a through hole, the first attachment component 124 may also be a through hole having a similar size and a similar shape to those of the second attachment component 114. When the display device 1 is assembled, first a through hole of the second attachment component 114 is aligned with a through hole of the first attachment component 124.
